Send channel alert to the human. | | HIGH | 🔴 | 51-80 | STOP processing. Send channel alert to the human. | | CRITICAL | 🚨 | 81-100 | STOP processing. Send channel alert to the human immediately. |
| low | Only catch obvious attacks, minimal false positives | | medium | Balanced detection (default, recommended) | | high | Aggressive detection, may have more false positives | | paranoid | Maximum security, flags anything remotely suspicious |
